A San Rafael man awaiting trial in a federal Ecstasy smuggling case was arraigned Friday on new charges of financial crime, according to court documents.

Investigators also raided a property Paul Grudzien owns in Fairfax, arrested the couple who live there, and found an elaborate marijuana growing operation involving secret doors and passages, a county drug investigator said.

Grudzien was scheduled to appear Friday in federal court in San Francisco to be arraigned on a charge of illegal financial structuring to evade reporting requirements, according to a filing by Assistant U.S. Attorney Adam Wright.

Because of the new financial charge, attorneys asked to vacate Grudzien's pending narcotics trial in May. He and his wife Meghan, who are now separated, were arrested last year on allegations they picked up a shipment of Ecstasy in Novato after it had been smuggled out of Canada by accused drug traffickers, according to court documents.

Wright said he expects to file a superceding indictment to reflect the financial structuring charges against Paul Grudzien. Federal authorities did not release details about the alleged financial crimes.

Defense attorneys for the Grudziens could not be reached for comment Friday evening.

Meanwhile, investigators conducted a search Friday morning at 10 Piper Lane, a Fairfax residence about 500 feet from Manor Elementary School. The homeowner is listed as Paul Grudzien, and the couple who live there are Kevin Andrew Kohley, 37, and Karen Kyfa Chen, 36. Kohley has also been listed as a resident of Grudzien's San Rafael home at 20 Tilden Court.

Investigators received information that Kohley, who is on probation for a drug case in Sonoma County, was cultivating marijuana at the home, said sheriff's Sgt. Pierre Ahuncain of the Marin County Major Crimes Task Force. Conducting a probation search at the residence, detectives seized more than 100 marijuana plants, several pounds of processed marijuana and $62,000 in cash.

Ahuncain said the home contained two secret chambers for the marijuana. One was behind a bookcase that was opened by pulling one of the books that was rigged up as a lever.

The other chamber was behind a mirror and contained an automated conveyor system — similar to the type used by dry cleaners to hang and move garments — on which to dry and rotate marijuana.

Investigators also found evidence that the suspects were splicing electricity from utility lines to run the marijuana growing operation, Ahuncain said. PG&E responded and shut off the power.

Kohley and Chen were booked into Marin County Jail on suspicion of cultivation and marijuana possession for sale. Their bail was set at $15,000.

Both were released on bail pending further review by prosecutors. They could not be reached for comment.
